xinput_calibrator and xorg driver

xinput_calibrator (version 0.7.5) is a X Window calibration application for touch screen device.
However, it only works with "evdev" xorg driver and cannot work with "libinput" xorg dirver.

To check which xorg driver is using for your touch screen device, we can execute the following command:

grep -e "Using input driver" /var/log/Xorg.0.log

If you find that "libinput" is using for your touch screen device, you have to create a configuration file to fix it:

cat > /usr/share/X11/xorg.conf.d/90-FixTouchDriver.conf << "EOF"

Section "InputClass"
    Identifier "You touch screen device Id"
    MatchIsTouchscreen          "on"
    MatchDevicePath              "/dev/input/event*"
    Driver                                "evdev"
EndSection

EOF

Then, xinput_calibrator should be able to get the correct values from the xorg driver.
